投影機及利用投影機調整環境光源的方法Projector and method for adjusting ambient light source by using projector

本發明係關於一種投影機及其調整方法，特別是一種可調整環境光源的投影機及其調整環境光源的方法。The invention relates to a projector and an adjustment method thereof, in particular to a projector capable of adjusting an ambient light source and a method for adjusting the ambient light source.

隨著生活水準的提升，投影機已經被廣泛的使用於日常生活中，例如辦公室或是家中。但投影機在投射影像時，容易受到外在的環境光源所干擾。因此使用者通常需要調整投影機的各種畫面參數設定，或是依照投影機所設定的情境模式，例如：明亮(Bright)、標準(Standard)、影片(Cinema)、遊戲(Game)及運動(Sports)等情境模式，來做調整，以增加投射影像的清晰度。With the improvement of living standards, projectors have been widely used in daily life, such as in the office or at home. However, when the projector projects an image, it is easily interfered by an external ambient light source. Therefore, the user usually needs to adjust various screen parameter settings of the projector, or according to the situation mode set by the projector, such as: Bright, Standard, Cinema, Game, and Sports (Sports) ) and other situational modes, to make adjustments to increase the clarity of the projected image.

但在先前技術中，當要調整投影機以適應不同環境光源變化時，通常是改變其內部之光學模組的亮度，亦即調整投影機內部之燈泡之亮度。但這種調整方式易造成燈泡過冷或是過熱，進而影響到投影機的使用壽命。因此只能夠微幅的調整燈泡之亮度，但如此一來反而會使得調整的效果不佳。However, in the prior art, when the projector is to be adjusted to adapt to changes in different ambient light sources, it is usually changed the brightness of the optical module inside, that is, the brightness of the bulb inside the projector. However, this adjustment method may cause the bulb to be too cold or overheated, which may affect the life of the projector. Therefore, only the brightness of the bulb can be adjusted slightly, but this will make the adjustment effect poor.

有鑑於此，因此有需要發明一種新的投影機及其調整環境光源的方法以解決先前技術的缺失。In view of this, there is a need to invent a new projector and its method of adjusting the ambient light source to solve the lack of prior art.

In an embodiment of the present invention, the light source control system 30 is a room control system or a power line communication system (Power Line Communication System), which can be used to control the brightness of the ambient light source emitted by the light source device 31, but The invention is not limited to this. The power line communication system is a system that utilizes the power line of the conference room to transmit the control signal. Since this technology has been widely used in related communication protocols, the principle will not be described herein. In addition, in an embodiment of the present invention, the light source device 31 is an electric lamp capable of adjusting the brightness of the light to emit an ambient light source, but the invention is not limited thereto.

本發明之投影機10可以經由光源控制系統30以控制光源設備31所發出的環境光源。投影機10包括影像處理單元11、訊號控制模組12、影像顯示單元13、光感應模組14與使用者操作介面20，彼此之間皆為電性連接。影像處理單元11用以處理投影機10要顯示出的投影影像，並且利用影像顯示單元13將影像投影至投影幕或是牆壁 上。其中影像處理單元11處理之程序還包括調整投影影像所要改變的畫面參數值，例如亮度(Brightness)、對比(Contrast)或是飽和度(Hue Saturation)等畫面參數值。訊號控制模組12則藉由通訊介面40與光源控制系統30電性連接，用以控制光源控制系統30，進而改變光源設備31所發出的環境光源之亮度。其中通訊介面40係為RS232介面，但本發明並不以此為限。光感應模組14用以偵測環境光源之亮度。當訊號控制模組12控制光源控制系統30以調整環境光源時，可以利用光感應模組14偵測光源設備31所發出的環境光源之亮度，並當作一回授訊號以傳遞回訊號控制模組12。如此一來，即可使得訊號控制模組12進行調整時能更精確。The projector 10 of the present invention can be controlled via the light source control system 30 to control the ambient light source emitted by the light source device 31. The projector 10 includes an image processing unit 11, a signal control module 12, an image display unit 13, a light sensing module 14, and a user operation interface 20, which are electrically connected to each other.

The program processed by the image processing unit 11 further includes adjusting picture parameter values to be changed by the projected image, such as brightness (Brightness), contrast (Contrast) or saturation (Hue Saturation). The signal control module 12 is electrically connected to the light source control system 30 through the communication interface 40 for controlling the light source control system 30, thereby changing the brightness of the ambient light source emitted by the light source device 31. The communication interface 40 is an RS232 interface, but the invention is not limited thereto. The light sensing module 14 is configured to detect the brightness of the ambient light source. When the signal control module 12 controls the light source control system 30 to adjust the ambient light source, the light sensing module 14 can be used to detect the brightness of the ambient light source emitted by the light source device 31, and used as a feedback signal to transmit the signal control mode. Group 12. In this way, the signal control module 12 can be adjusted more accurately.

使用者操作介面20係為提供使用者用以操作投影機10之介面，除了可以控制投影機10投影出的影像的畫面參數之外，還可用以控制環境光源之亮度。使用者操作介面20係包括供使用者選擇執行之情境模式21與環境光源控制模式22。情境模式21可包括標準(Standard)模式21a、明亮(Bright)模式21b與影片(Cinema)模式21c，但本發明並不以上述的三種情境模式為限。當使用者選擇執行情境模式21後，影像處理單元11會依所選擇的模式以改變影像的畫面參數，並且訊號控制模組12亦同時控制光源控制系統30以改變環境光源。另一方面，使用者亦可選擇執行環境光源控制模式22以直接改變環境光源。關於利用投影機10改變環境光源之方式在之後會有詳細的敘述。The user operation interface 20 is for providing a user interface for operating the projector 10. In addition to controlling the picture parameters of the image projected by the projector 10, it can also be used to control the brightness of the ambient light source. The user interface 20 includes a context mode 21 and an ambient light source control mode 22 for the user to select for execution. The context mode 21 may include a standard mode 21a, a bright mode 21b, and a Cinema mode 21c, but the present invention is not limited to the above three context modes. After the user selects to execute the context mode 21, the image processing unit 11 changes the picture parameters of the image according to the selected mode, and the signal control module 12 also controls the light source control system 30 to change the ambient light source. Alternatively, the user may choose to execute the ambient light source control mode 22 to directly change the ambient light source. The manner in which the ambient light source is changed by the projector 10 will be described in detail later.

接下來請參考圖2關於本發明利用投影機控制環境光 源之步驟流程圖。此處需注意的是，以下雖以具有投影機10之影像播放系統1為例說明本發明之控制環境光源之方法，但本發明之控制環境光源之方法並不以使用在投影機10及影像播放系統1為限。Next, please refer to FIG. 2 regarding the use of the projector to control ambient light according to the present invention. Step flow chart of the source. It should be noted that the following describes the method for controlling the ambient light source of the present invention by taking the video playback system 1 with the projector 10 as an example. However, the method for controlling the ambient light source of the present invention is not used in the projector 10 and the image. The playback system 1 is limited.

如圖2所示，本發明首先進行步驟201，藉由使用者操作介面輸入一控制訊號。As shown in FIG. 2, the present invention first performs step 201, and inputs a control signal through a user operation interface.

在步驟201中，投影機10提供使用者藉由使用者操作介面20以輸入控制訊號。輸入之控制訊號可為執行情境模式21之訊號或是執行環境光源控制模式22之訊號，但本發明並不以上述訊號的種類為限。例如，控制訊號亦可為調整影像之亮度、對比或是飽和度等畫面參數之訊號。In step 201, the projector 10 provides a user with a user control interface 20 to input a control signal. The input control signal may be the signal of the execution of the situation mode 21 or the execution of the ambient light source control mode 22, but the invention is not limited to the types of the above signals. For example, the control signal can also be a signal for adjusting the brightness, contrast or saturation of the image parameters.

接著本發明進行步驟202，根據該控制訊號以投影一投影影像。Next, the present invention proceeds to step 202 to project a projected image based on the control signal.

在步驟202中，影像處理單元11藉由步驟201中所選擇的模式，而對要投影的影像進行畫面參數上的調整，例如調整投影影像之亮度、對比或是飽和度等畫面參數值，或是藉由情境模式21以自動調整投影影像。接著再藉由影像顯示單元13投影出已經調整過的投影影像。In step 202, the image processing unit 11 performs image parameter adjustment on the image to be projected by using the mode selected in step 201, for example, adjusting the brightness, contrast, or saturation of the projected image, or The scene mode 21 is used to automatically adjust the projected image. The projected image that has been adjusted is then projected by the image display unit 13.

本發明在進行步驟202時，可同時或接著進行步驟203，根據該控制訊號對環境光源進行調整。When the method proceeds to step 202, the method may perform step 203 simultaneously or subsequently, and adjust the ambient light source according to the control signal.

在步驟203中，訊號控制模組12同時藉由步驟201中所選擇的模式，經由通訊介面40對光源控制系統30進行控制，藉以控制光源設備31以調整環境光源之亮度。In step 203, the signal control module 12 simultaneously controls the light source control system 30 via the communication interface 40 by the mode selected in step 201, thereby controlling the light source device 31 to adjust the brightness of the ambient light source.

在步驟201中，若在使用者操作介面20中選擇執行標 準模式21a時，即可視為此時投影機10為一般正常之使用狀況。根據實驗的結果，環境光源對比度(Ambient Contrast Ratio)，應在20：1到10：1之間才能讓使用者有較佳的觀賞效果。其中環境光源對比度之定義係為投影機10的照度與環境光源之亮度之比例。因此在標準模式21a下調整環境光源的調整公式如下： In step 201, if the execution of the standard mode 21a is selected in the user operation interface 20, it can be considered that the projector 10 is in a normal normal use condition at this time. According to the experimental results, the Ambient Contrast Ratio should be between 20:1 and 10:1 to give the user a better viewing effect. The definition of the ambient light source contrast is the ratio of the illumination of the projector 10 to the brightness of the ambient light source. Therefore, the adjustment formula for adjusting the ambient light source in the standard mode 21a is as follows:

其中L A 為要控制之環境光源。L PS 為標準模式21a下投影機10的平均照度。以一般具有2000流明(lumens)的投影機10而言，標準模式21a下的平均照度大約為1300勒克斯(Lux)。L S 為光感應模組14偵測到的環境光源。訊號控制模組12係將環境光源調整到可符合上述的環境光源對比度之範圍中。Where L A is the ambient light source to be controlled. L PS is the average illuminance of the projector 10 in the standard mode 21a. For a projector 10 typically having 2000 lumens, the average illumination at standard mode 21a is approximately 1300 lux. L S is an ambient light source detected by the light sensing module 14 . The signal control module 12 adjusts the ambient light source to a range that satisfies the ambient light source contrast described above.

若在明亮模式21b下，則代表使用者選擇在環境光源的亮度提高時使用投影機10。在此情況下會使得投影機10投影出的投影影像在暗部的細節因為環境光源之影響而顯得模糊。根據利用投影機10顯示灰階訊號的方式實驗的結果，若設定以具有32階的灰階訊號只能損失4~6階為許可範圍之情況下，此時的環境光源對比度應該要保持在2.67：1到2：1之間才能得到清楚的投影影像。因此在明亮模式21b下調整環境光源的調整公式如下： In the bright mode 21b, the projector 10 is selected to be used when the brightness of the ambient light source is increased. In this case, the projection image projected by the projector 10 is blurred in the dark portion due to the influence of the ambient light source. According to the experimental results of the manner in which the gray scale signal is displayed by the projector 10, if the gray scale signal with 32 steps can be set to lose only 4 to 6 steps, the ambient light source contrast should be kept at 2.67. : A clear projected image can be obtained between 1 and 2:1. Therefore, the adjustment formula for adjusting the ambient light source in the bright mode 21b is as follows:

其中L A 為要控制之環境光源，L PR 為明亮模式21b下投影機10的平均照度。在明亮模式21b下投影機10的平均照度大約為1800勒克斯(Lux)。L S 為光感應模組14偵測到的環境光源。Where L A is the ambient light source to be controlled, and L PR is the average illuminance of the projector 10 in the bright mode 21b. The average illuminance of the projector 10 in the bright mode 21b is approximately 1800 lux. L S is an ambient light source detected by the light sensing module 14 .

當在執行影片模式21c時，由於一般使用者都會在較暗的環境光源下，利用投影機10觀賞影片。所以此時就需要注意投影影像的對比與暗部細節。根據實驗的結果，若要求具有32階的灰階訊號之任一暗部細節都必須可以清楚辨識，此時的環境光源對比度應該要保持在100：1到33.3：1之間才能得到清楚的投影影像。因此在影片模式21c下調整環境光源的調整公式如下： When the movie mode 21c is executed, since the general user will view the movie using the projector 10 under a dark ambient light source. Therefore, you need to pay attention to the contrast and dark details of the projected image. According to the results of the experiment, if any dark part of the gray-order signal with 32-order order is required to be clearly identified, the ambient light source contrast should be kept between 100:1 and 33.3:1 to obtain a clear projected image. . Therefore, the adjustment formula for adjusting the ambient light source in the film mode 21c is as follows:

其中L A 為要控制之環境光源。L PV 為影片模式21c下的平均照度。以一般具有2000流明(lumens)的投影機10而言，影片模式21c下的平均照度大約為1000勒克斯(Lux)。L S 為光感應模組14偵測到的環境光源。Where L A is the ambient light source to be controlled. L PV is the average illuminance in film mode 21c. In the case of a projector 10 generally having 2000 lumens, the average illumination at film mode 21c is approximately 1000 lux. L S is an ambient light source detected by the light sensing module 14 .

訊號控制模組12係分別藉由上述的公式以控制光源控制系統30，將環境光源調整到各個情境模式所設定的環境光源對比度之範圍當中。The signal control module 12 controls the light source control system 30 by the above formula to adjust the ambient light source to the range of the ambient light source contrast set by each context mode.

另一方面，使用者亦可以直接選取環境光源控制模式22，以藉由訊號控制模組12直接提高或是降低環境光源之亮度。On the other hand, the user can also directly select the ambient light source control mode 22 to directly increase or decrease the brightness of the ambient light source by the signal control module 12.

本發明接著進行步驟204，偵測環境光源之亮度。The present invention then proceeds to step 204 to detect the brightness of the ambient light source.

在步驟204中，本發明接著利用光感應模組14偵測此時光源設備31所發出的環境光源之亮度，並將偵測到的環境光源之亮度當作回授訊號以回傳到訊號控制模組12。In step 204, the present invention then uses the light sensing module 14 to detect the brightness of the ambient light source emitted by the light source device 31, and uses the detected brightness of the ambient light source as a feedback signal to be transmitted back to the signal control. Module 12.

最後本發明進行步驟205，判斷該環境光源是否已調整完成。Finally, the present invention proceeds to step 205 to determine whether the ambient light source has been adjusted.

在步驟205中，訊號控制模組12藉由回授訊號以判斷環境光源是否已調整完成。若訊號控制模組12判斷環境光源尚未調整完成，就回到步驟203再進行調整，直到環境光源之亮度調整到各模式所應對應的環境光源對比度之範圍內。以執行標準模式21a之實施例為例，若步驟204中光感應模組14偵測到的環境光源之亮度小於投影機10的平均照度之20分之一，訊號控制模組12就會控制光源控制系統30以提高環境光源之亮度。若光感應模組14偵測到的環境光源之亮度大於投影機10的平均照度之10分之一，訊號控制模組12即控制光源控制系統30以降低環境光源之亮度。訊號控制模組12會持續調整環境光源，直到環境光源之亮度調整到標準模式21a所應對應的範圍內為止。In step 205, the signal control module 12 determines whether the ambient light source has been adjusted by the feedback signal. If the signal control module 12 determines that the ambient light source has not been adjusted, it returns to step 203 and then adjusts until the brightness of the ambient light source is adjusted to the range of the ambient light source corresponding to each mode. For example, in the embodiment of the standard mode 21a, if the brightness of the ambient light source detected by the light sensing module 14 in step 204 is less than one-twentieth of the average illuminance of the projector 10, the signal control module 12 controls the light source. Control system 30 is used to increase the brightness of the ambient light source. If the brightness of the ambient light source detected by the light sensing module 14 is greater than one tenth of the average illuminance of the projector 10, the signal control module 12 controls the light source control system 30 to reduce the brightness of the ambient light source. The signal control module 12 continuously adjusts the ambient light source until the brightness of the ambient light source is adjusted to within the range corresponding to the standard mode 21a.

另一方面，由於在明亮模式21b與影片模式21c下的調整方式與在標準模式21a下的方式類似，僅為改變其環境光源對比度之值，故在此不再贅述其調整流程。On the other hand, since the adjustment mode in the bright mode 21b and the film mode 21c is similar to that in the standard mode 21a, only the value of the contrast of the ambient light source is changed, and the adjustment flow thereof will not be described herein.

若環境光源的亮度已經在所選取的情境模式所對應的範圍內，就可以結束利用投影機控制環境光源之流程。If the brightness of the ambient light source is already within the range corresponding to the selected context mode, the process of controlling the ambient light source by the projector can be ended.

此處需注意的是，本發明之利用投影機控制環境光源之方法並不以上述之步驟次序為限，只要能達成本發明之目的，上述之步驟次序亦可加以改變。It should be noted here that the method for controlling the ambient light source by the projector of the present invention is not limited to the above-described sequence of steps, and the order of the above steps may be changed as long as the object of the present invention can be achieved.

綜上所陳，本發明無論就目的、手段及功效，在在均顯示其迥異於習知技術之特徵，懇請 貴審查委員明察，早日賜准專利，俾嘉惠社會，實感德便。惟應注意的是，上述諸多實施例僅係為了便於說明而舉例而已，本發明所主張之權利範圍自應以申請專利範圍所述為準，而非僅限於上述實施例。To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examination and express the patent as soon as possible. It should be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the invention is intended to be limited by the scope of the claims.
